Overview: Vida Cantina (Portsmouth, N.H.) • P's & Q's Market (Portland, Ore.) • Ataula (Portland, Ore.) This trip, Guy Fieri's going coast-to-coast for righteous flavor. In New Hampshire, a modern cantina puttin' out the pork - from belly tacos to a pig's head platter. In Portland, a Woodlawn Park neighborhood market cookin' up grandma's take on biscuits and gravy, plus a funky polenta sandwich. And in northwest Portland, a husband-and-wife relivin' the Spanish food he grew up with, servin' outrageous octopus and other creative tapas.
